SMOKE-CONDUCTOR AND VENTILATOR FOR CARS.

SPECIFICATION forming part of Letters Patent No. 391,263, dated October16, 1888.

Application filed December 28, 1857. Serial No. 259232. (No model.)

To all whom it may concern.-

Be' it known that I, ALFRED S. DIILES, of Brooklyn, county of Kings, andState of New York, have invented certain new and useful Improvements inSmoke-Conductors and Ventilators for Cars, of which the following is afull, clear, and exact description, reference being had to theaccompanying drawings, and to the letters of reference marked thereon.

My invention has relation to means or apparates for conducting the smokeand products of combustion from a locomotive rearward over the carsin atrain and for ventilating the cars or stoves or closets therein, whichapparatus I call a smoke-conductor and ventilator.

The object of my invention is to provide a train of cars with a compact,simple, and efficient smoke-conductor, which, when the train is moving,will carry the smoke and other products of combustion from theloeomotiverearward to be discharged at the end of the train, which conductor willnot interfere with the draft from the smokestack while the locomotive isstanding or backing, or while the fire is being accelerated, and toutilize this conductor as part of a system for ventilating the cars oraccessories therein, thus obviating the disagreeable effects of smoke,850., from the smoke-stack, and insuring a proper circulation of airthrough the cars or part; thereof without admit-ting smoke or gases fromone car into another.

To accomplishall of this my improvements involve certain new and usefularrangements or combinations of parts and principles of operation, aswill be herein first fully described, and then pointed out in theclaims.

In the accompanying drawings,forming part of this specification, Figure1 is a side view, and Fig. 2 a plan, of a train composed of aloeomotive, tender, and one car having my improved device or apparatusapplied in accordance with my invention, and indicating the manner inwhich it may be adopted on a train of any length. Fig. 3 is across-section showing the branches of the conductor on each side of theroof. Fig. 4 is aviewin elevation, and Fig. 5 a view in section, showingthe ends of the conductor made flexible in order to yield to themovements of the cars and yet preserve the desired union with the partsto which coupled. Fig. 6 is a plan showing the hinged sections asmounted 011 the locomotive and turned back out of the way. Figs. 7 and 8are sectional views of fragments of the conductor, showing differentpositions which the air-injector will automatically assume as the carmoves. Fig. 9 isa sectional elevation indicating the connection betweenthe conductor on the exterior of the car and a ventilator-pipecommunicating with various points on the interior. Fig. 10 is a similarview showing the smoke-pipe from the car-stove discharging into theexterior conductor.

In all the figures like letters of reference wherever they occurindicate corresponding parts.

A is the smoke-stack ofthe locomotive. It is desirable that this shouldbe left free attop, so that smoke, tic, may be discharged therefromwithouthinderance,so that whether moving forward or backward or standingstill the draft will not be obstructed, but may be accelerated at anytime, (as by any of the forms of blowers.)

3 is the mouth or funnel of my apparatus, open toward the front,extending to the discharge end of the smoke-stack, located a littleabove it, but not projecting over it. This month or funnel is of amplesize to receive all the products of combustion which may leave thesmoke-stack, and it communicates with two open pipes or conduits leadingrearward, the two together being of size suiiicient to freely carry allthat may be injected into them. These conductors spread, as at O C,toward the cab, so as to escape the whistle, the bell, and otheradjuncts which may be mounted on the locomotive. The sections 0 O aresupported on the cab, and are supplied with sections 0' C", which arehinged, as at a, and intended to reach about the length of the tender tothe first car of the train. By hinging the sections 0 O as shown, eitheror both may be swung forward, as in Fig. 6, to clear the space over thetender, so the latter may be loaded at any time. Sections of theconductor, as C C", extend over the cars. These are mounted on the roofsnear the edges, so as not to add to the width of the cars, and below themain central parts of the roofs, so as not to add to the height of thecars. In this position they are in no danger of being damaged ordisplaced. The several sections constitute the Q egress conductors, andwhen connected or coupled up they serve to carry the smoke, 800.,rearward to the end of the train,discharging at the rear. 1

The couplings should be made automatic and should be flexible, so as topermit movements of one section with respect to the other withoutdestroying the continuity of the pipe. I therefore construct thecouplings as indicated in Figs. 4 and 5, .wherein b b are flangesadapted to abut against each other. a o are springs which, when oneflange is brought against the other, will snap over the margins and holdthem with sufficient firmness, but not so as to prevent them from beingdrawn asunder, (as when the cars are uncoupled.)

d is a spiral spring united with flange b and with the end of theconductor-section, and e is a cloth or other flexible covering for thespring d. One of these couplings is mounted on each end of each. sectionof the conductor.

As the train moves forward,the smoke, 850., areprojected into the funnelB and through the branches of the conductor. To facilitate its rearwardpassage and to keep the conductor free of dust and ashes, (as well as toserve other purposes) I mount air-injectors, as f f, on the conductor.These each consist of two parts, and are hinged, as at 9, over openings71, in such manner that they will direct cur rents of air into andthrough the openings h, no matter in which direction the car may bemoving and these air-currents eject the contents of the conductors in amanner which will be readily understood. As many of these injectors maybe supplied as may be desired.-

There being thusaconstantcurrent maintained through the conductors, Iemploy them to advantage in ventilating the cars and various partsthereof. For instance, in the region of one of the openings h, I unite aventilato'r-pipe, D, with the conductor. This pipe may have any numberof registers, as t t, at various heights in the car. One of theregisters being open and the car in motion, foul air is drawn out of thecar on principles readily under-. stood. If the car remains stationary,any naturally-ascending currents will find their way through opening hto the exterior air. Under no circumstances will they be discharged fromone car to pass into the next.

To prevent cinders, 850., from lodging in the ventilator-pipe, I supplyit with an automatically-operatinghalfdamper,asatlc. This is turned bythe passing current, so that said current will be deflected up and pastthe orifice governed by the damper. In like manner I connect thesmoke-pipe of the car-stove E with the exterior conductor, and am thusenabled to facilitate the draft of the stove and deliver its products ofcombustion at the rear of the train instead, as heretofore, partly in anadjacent car. When at rest, thedraftis directly out through opening Iit. These examples will suffice to show the manner of utilizing theapparatus in connectionwith any part of the car. I especially intend toprovide in a similar manner for the ventilation of the various closetsin the car.

By the means described I am enabled to thoroughly ventilate all parts ofthe car or train without in any way interfering with the usualoperations of the various adjuncts of the train'and accomplishing thepurpose or object of the invention, as previously set forth.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is-

1. The open mouth or funnel located in rear of and above the dischargeend of the smoke-stack, combined with a smoke-conductor leadingrearward, divided into two branches, each having a hinged section,substantially as and for the purposes set forth.

2. The combination, with the funnel, of the two sections of theconductor spread and extending rearward on the sides of the train, eachsection being provided with a hinged portion and with automaticcouplings, substantially as shown and described.

3. The hinged sections of the smoke-conductor, each carrying one portionof an automatic coupling,combined with the other sec tions of thesmoke-conductor, and arranged to be swung forward to clear the tender,substantially as shown and described.

4. In a smoke-conductor of the character herein set forth, the varioussections each provided with flexible and automatic end couplings, andwith automatically-operating airinjectors, for the purposes and objectsexplained.

5. The smoke-conductor extending on both sides of the root of the carand provided with smoke-conductor in the region of theopeninggove'rnediby one of the air-injectors, substantially as and forthe purposes set forth.

In testimony that I claim the foregoingI have hereunto set my hand inthe presence of two witnesses.
